Abstract
In order to provide a cement clinker production line with a calcinator connected to the rotary kiln and including a separate rotary drum-type reactor with the objective to safely burn even coarse secondary fuels in the drum-type reactor and also to evenly and effectively transfer the released heat energy to the cement raw meal, it is proposed in accordance with the invention to introduce into the rotary drum-type reactor on the inlet side for the solids a partial stream line of the tertiary air guided from the clinker cooler to the calcinator, a highly ignitable fuel, the low ignitable or low flammable secondary fuel and a partial stream line for the cement raw meal and to connect the exit side for the material on the rotary drum-type reactor via a line for carrying out the solid residues to the tertiary air channel and/or the rotary kiln exit gas channel of the calcinator and/or to the inlet chamber of the rotary kiln.
